SPECIFICATION forming part of Letters Patent No. 429,020, dated May 27,1890.

Application filed March 15, 1889. Serial No. 303,412. (No model.)

To all whom it may concern.-

Be it known that I, JOHN DULLENTY, a citizen of the United States,residing at WVaverly, in the county of Lancaster and State of Nebraska,have invented certain new and useful Improvements in Corn-Cultivators;and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the letters and figures ofreference marked thereon, which form a part of this specification.

This invention relates to wheel-Cultivators; and it consists in thenovel features which will be hereinafter more fully described andclaimed, and which are shown in the annexed drawings, in which Figure lis a perspective view, parts being broken away, of a cultivatorembodying my invention; Fig. 2, a side View of the cultivator; Fig. 3, aperspective view of the shovel; Fig. 4, a front view of the shovel; Fig.5, a side view, partly in section, of the means for connecting thecultivator-gang to the yokestandards; Fig. 6, a bottom perspective viewof the casting; Fig. 7, a perspective view of the eyebolt; Fig. 8, afront view, partly in section, of the connection between the standards;Fig. 9, a top detail view showing the means for fastening the clevis tothe casting; Fig. 10, a perspective view of the catch; Fig. ll, a detailview showing the means for connecting the lever to the yoke; Fig. 12, adetail view showing the means for connecting the shovel to the standard.

The crank-axle O, of ordinaryconstruction, is composed of bar 0 and thecastings C, bolted to its ends, having the axle-arms G on which aremounted the supporting-wheels C The tongue D is secured to the axle atits inner end by the king-bolt d, the usual wearcastings beinginterposed between the rubbing parts. The arch S has its ends bent downto form the vertical standards 8, and its middle portion 5 curvedforwardly, and is strengthened by the supplemental bar S, which isbolted at its ends to the vertical standards 8. The arch S is bypreference composed of gas-pipe and is supported on the wheels 7 7, onesecured upon each side of the tongue D, and the bar S is flat and ofcorresponding shape with the bar S and is arranged to come on the underside of the tongue and bear on the under sides of the said wheels 7 7.These wheels 7 7 are mounted on arms that project from blocks or plates5 5, which are secured to the sides of the tongue.

The vertical standards T, parallel with the standards .9, are secured tothe bar S, and the two sets of standards T s are braced by the rods Rand R, as shown, and have corresponding openings to receive the bolt f,which connects the lower ends of the standards and has the blocks 2 2and 3 placed thereon. The outer ends of the blocks 2 2 are indented toreceive the standards T s, which are partially embedded therein. Theinner ends of the blocks 2 2 have bearings s, which are fitted in theends of the block 3.

The coupling 4. is mounted on the block 3 and is adjustable thereon,being held by the eyebolt U, which is fitted in a mortise in the underside of the coupling 4 and embracing the block 3. The eyebolt istightened by the nut n on its threaded stem.

The clevis B, to which the cultivator-gangs B are attached, is securedto the coupling 4 in the usual manner, and may be held fast or limitedin its lateral movement in either direction by the stops A, which arepivoted to a rear extension of the coupling 4. The pins a, projectingfrom the sides of the coupling, engage with and hold the stops A inproper position. WVhen both stops are thrown down, they embrace thesides of the clevis and prevent its movement in either direction. Byturning down the right stop only the clevis will be limited in itsmovement to the right. The same is true if the left stop he the only oneturned down, the clevis in this case being limited in its movement tothe left.

The gang of cultivators are raised and lowered by means of thehand-levers E and the chains E connecting them with the said handlevers,which latter are held fast by the latches E which engage with thesegments E.

The seat-bars 12 12 rest on the axle midway of their ends and have theirfront ends adj ustably connected with the vertical bars 11 11, which areplaced between the arch S and the bar S.

The operating-lever 10 is mounted on the crank-arm 8, and is connectedwith the arch S a short distance from its end. The bracket M, secured tothe arch, has a recess m in one side in which is fitted the block K,that has the gudgeon k. The lever is placed on this gudgeon, and is heldin place by the bolt w,which passes through the block K and bracket M.The washer II, placed between the head of the bolt and the end of thegudgeon k, prevents any binding of the lever 10 between the block K andthe head of the bolt. The lever 10 extends within convenient reach ofthe drivers seat, and can be operated to move the frame to the right orleft, as required, as will be readily understood.

The hook (3, attached to one of the blocks 5, is adapted to enter theopening W in the bar S and hold the arch steady when transporting themachine.

The shovel 1b is pointed, as most clearly shown in Fig. l, and its edgesare approximately parallel and curve to one side, the shovel curvingrearwardly and to one side, after the fashion of a mold-board.

The casting or coupling 17, secured to the rear of the shovel, has atransverse groove 20, through which and the standard 15 thefastening-bolt 18 passes. The front side of the standard is curved andfits a corresponding curved seat in the said casting. By loosening thebolt the shovel can be adjusted laterally on the standard. The rear sideof the standard is grooved and is spanned by the plate 19 on the backend of the bolt.

Ilaving thus described my invention, what I claim, and desire to secureby Letters Patent, 1s

1. In a wheel-cultivator, the combination, with the frame comprising thearch, which has two parallel bars S and S, the one above the other, ofthe tongue having pivotal connection with the said frame and passingbetween the bars S and S, and the rollers journaled to the sides of thetongue and adapted to obtain a bearing on the said bars S and S,substantially as described.

2. In a \vheel-cnltivator, the combination,

with the frame comprising the arch, which has two parallel bars S and S,said bars curving outward between their ends, of the tongue havingpivotal connection with the frame and passing between the said bars Sand S, and having a roller-bearing to travel between the bars on thesaid curved portion, substantially as described.

A Wheel-cultivator comprising the axle, the arch connected with andbraced to the axle and comprising the parallel bars S and S, the ends ofthe bar S being bent down to form the standards 8, the standards T T,parallel with the standards .9 and connected with the bar S, thecultivator-gangs supported between the lower ends of the standards 5 andT and adjustable at their rear ends by means of chain E, lever Eratchet-segment E, and latch E the tongue pivotally connected with theaxle and passing between the bars S and S, the rollers journaled on thesides of the tongue and adapted to travel on the lower bar S, and thehand-lever 10 for moving the tongue, substantially as described.

4. In a wheel-cultivator, the combination, with the vertical standardsand the bolt f, having the block 3, of the coupling, the eyebolt fittedin a mortise or recess in one side of the coupling, and the nut 91.,substantially as described.

5. In a wheel-cultivator, the combination of the frame having standards,as s and T, the blocks 2 2 and 3 interlocking at their opposite ends,the bolt f, passing through the standards and the said blocks, thecoupling 4, placed on the block 3 and having a recess in its side, theeyebolt U, inserted in said recess in the coupling for holding the sameon the block, and the cultivator-gang connected with the said coupling,substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
